Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2011-4136 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- django (PyPI): affected all versions; fixed in 1.2.7, 1.3.1\n- django (PyPI): affected all versions; fixed in 1.2.7\n- django (PyPI): affected from 1.3; fixed in 1.3.1\n- Django (PyPI): affected all versions; fixed in 1.2.7\n- Django (PyPI): affected from 1.3; fixed in 1.3.1\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2011-4136/ (Markdown: https://insights.sbomify.com/CVE-2011-4136/index.md)","id":"CVE-2011-4136","markdown":"https://insights.sbomify.com/CVE-2011-4136/index.md","name":"CVE-2011-4136","record":{"aliases":["DEBIAN-CVE-2011-4136","GHSA-x88j-93vc-wpmp","PYSEC-2011-1"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Django web framework","requires_auth":"low_privilege","summary":"Remote attackers can modify user sessions by exploiting a namespace collision in Django's cache-based session storage, requiring cache backend configuration.","user_interaction":"not_required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"django","vendor":"djangoproject"}],"cvss":{"score":5.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"django.contrib.sessions in Django before 1.2.7 and 1.3.x before 1.3.1, when session data is stored in the cache, uses the root namespace for both session identifiers and application-data keys, which allows remote attackers to modify a session by triggering use of a key that is equal to that session's identifier.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Session manipulation in Django","id":"CVE-2011-4136","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"djangoproject:django","products":["djangoproject:django"],"type":"business_logic","year":"2011"},"n_packages":5,"n_references":8,"next":{"headline":"Denial of service in django","id":"CVE-2011-4137"},"packages":[{"ecosystem":"PyPI","fixed":["1.2.7"],"introduced":["0"],"last_affected":[],"package":"Django","purl":null,"source":"GHSA-x88j-93vc-wpmp"},{"ecosystem":"PyPI","fixed":["1.3.1"],"introduced":["1.3"],"last_affected":[],"package":"Django","purl":null,"source":"GHSA-x88j-93vc-wpmp"},{"ecosystem":"PyPI","fixed":["1.2.7","1.3.1"],"introduced":["0","1.3"],"last_affected":[],"package":"django","purl":"pkg:pypi/django","source":"PYSEC-2011-1"},{"ecosystem":"PyPI","fixed":["1.2.7"],"introduced":["0"],"last_affected":[],"package":"django","purl":"pkg:pypi/django","source":"GHSA-x88j-93vc-wpmp"},{"ecosystem":"PyPI","fixed":["1.3.1"],"introduced":["1.3"],"last_affected":[],"package":"django","purl":"pkg:pypi/django","source":"GHSA-x88j-93vc-wpmp"}],"prev":{"headline":"Path traversal in n/a","id":"CVE-2011-4135"},"products":["n/a"],"published":"2011-10-19","related":[{"cvss_score":9.8,"headline":"Privilege abuse in GenericInlineModelAdmin","id":"CVE-2026-4277","kev_date_added":null,"published":"2026-04-07"},{"cvss_score":9.8,"headline":"Django SQL injection in HasKey(lhs, rhs) on Oracle","id":"CVE-2024-53908","kev_date_added":null,"published":"2024-12-06"},{"cvss_score":9.8,"headline":"Django SQL injection vulnerability","id":"CVE-2024-42005","kev_date_added":null,"published":"2024-08-07"},{"cvss_score":9.8,"headline":"Django bypasses validation when using one form field to upload multiple files","id":"CVE-2023-31047","kev_date_added":null,"published":"2023-05-07"},{"cvss_score":9.8,"headline":"Django `Trunc()` and `Extract()` database functions vulnerable to SQL Injection","id":"CVE-2022-34265","kev_date_added":null,"published":"2022-07-04"},{"cvss_score":9.8,"headline":"SQL Injection in Django","id":"CVE-2021-35042","kev_date_added":null,"published":"2021-07-02"},{"cvss_score":9.8,"headline":"SQL injection in Django","id":"CVE-2020-7471","kev_date_added":null,"published":"2020-02-03"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can modify user sessions by exploiting a namespace collision in Django's cache-based session storage, requiring cache backend configuration.","url":"https://insights.sbomify.com/CVE-2011-4136/"}
